(Cl. 242-555) ABSTRACT 0FTHE DISCLOSURE This invention relates to a paper roll holder thatpermits each of a plurality of paper rolls mounted on a common shaft topay off paper at a rotation rate that is independent of the rotationrate of the other rolls. Means are provided to position each rollaxially along the shaft and independently retard the rotation of eachroll.

My invention relates to a holder for rolls of paper and in particular toa holder to operate in conjunction with paper cutters, rewindingmachines, embossing machines and the like. In paper working machinery itis desirable to perform operations on sheets of paper coming from morethan one roll of paper at the same time. It is not possible, however, tomount paper rolls of different diameters and different widths or axiallengths on a common shaft because the largest diameter roll does nothave to rotate as fast as the smallest diameter roll to deliver strippaper at the same linear velocity. The result of a plurality ofdifferent diameter rolls on a common shaft would be that the paper wouldbe delivered at different linear velocities or some of the paper wouldbind and tear. In a paper cutter, for example, if several strips ofpaper are being cut into small sheets, the strips must move at the samelinear velocity or the sheets will not be of uniform size.

It is an object of my invention to provide an improved Y paper rollholder which permits rolls of paper of different diameters to be mountedin side by side relationship on a common shaft.

It is another object of my invention to provide an improved paper rollholder which allows rolls of paper of different diameters and widths oraxial lengths mounted in side by side relationship to rotate atdifferent angular velocities.

It is a further object of my invention to provide a multiple roll paperholder in which each yroll is independently adjustable in position alonga shaft without the use of intermediate supports or standards.

It is yet another object of my invention to provide a multiple rollpaper holder having a common shaft on which each roll is independentlyretarded without the use of intermediate supports or standards.

My invention accomplishes these objects by construct*` ing a stationaryshaft with a plurality of sleeves rotatably mounted on the stationaryshaft. The rolls of paper are then mounted on the sleeves. Means areprovided to adjust the position of each roll along the shaft so that thepaper will line up with a following machine, such as a paper cutter.Each roll is also independently retarded with a friction wheel mountedon each of the sleeves.

The teachings of the invention produce a paper roll holder in which eachroll of a plurality of rolls is free to rotate at an angular velocitywhich is independent of the angular velocity of the other rolls.

The prior art uses a paper roll holder comprising two stands orstandards supporting a simple shaft which holds one roll of paper andturns with the paper roll. It is not practical to mount a plurality ofthese paper roll holders side by side to get the desired multiple sourceof supply of sheet paper strips because the room taken between the paperrolls by the standards and allowances for different roll widths would beexcessive.

For example, if three paper roll holders of the prior art were placedside by side, four standards or supports would be the minimum required.Two would be end Standards each holding one end of the shaft; two wouldbe intermediate standards each holding one end of two shafts. Becausethe width or axial length of the paper rolls varies, the intermediatestandards would limit the mounting of rolls of paper which are widerthan the spacing between the adjacent standards.

My invention obviates the necessity of intermediate standards byrequiring only two end standards.

For a better understanding of the invention reference may be had to theaccompanying drawings in which:

FIGURE l is a perspective view showing an application of my invention;

FIGURE 2 is a partial longitudinal section through the embodiment of theinvention shown in FlG. l; and

FIGURE 3 is a detail of the construction of the end retarding wheels.

Referring to FIGS. 1 and 2, where like numerals refer to like parts,there is illustrated an embodimentof my invention applied to three rollsof paper 10, 12 and 14 of different diameters and different axiallengths, Each of the rolls is. mounted on one of three sleeves 18, 20and 22 which are carried on a shaft 16. The shaft 16 is supported bysupports or standards 36 and 38. The paper rolls are secured to thesleeves by removable collars such as the collars 24 and 26, securingroll 10 to sleeve 18.

Removable rings 31 may be attached to the end sleeves 18 and 22 toprovide thrust bearing surfaces for lateral adjustment of the positionof the paper rolls by any suitable means such as the lateral adjustmentboxes 68 used with paper roll holders of the prior art. Lateraladjustment of the sleeves along the shaft is necessary to line up thepaper sheets with following machinery, such as a paper cutter.

Friction wheels such as wheel 28 may be mounted on the sleeves 18, 20and 22 to retard the angular velocity of the paper rolls and preventoverrunning of the strip paper as the rolls are rotated by the paperbeing pulled off the rolls by a machine (not shown) such as a papercutter.

The middle sleeve 20 can be adjusted along' the shaft 16 by means of aremovable combination retarding and position adjustment clamp or carrier5ft. The clamp 54 is secured to the shaft 16 by pin 80 or by anysuitable means such as allen screws or keyways. A threaded member 56 isprovided in the clamp 54 to engage a brake band carrier 78 to move thewheel 60` and thus the sleeve 20 along the shaft 16 and to hold thesleeve in the desired position along the shaft 16 while the sleeverotates. The end of the threaded member 56 is engaged with a carrier forthrust and friction means such as the externally contracting brake bands58 mounted about the friction wheel 60. The friction wheel 60 isprovided with a groove dened by two flanges which function in a mannersimilar to thrust rings 31 to move the sleeve 20 along the shaft 16. Thebrake bands 58 may be tightened by means of screw 62 on the frictionwheel 60 to provide the desired retardation to the paper roll 12.

The other end of the threaded member 56 is engaged with clamp or carrier54 and is provided with a handle 59 and lock nuts 61.

It will be understood that to move the sleeve 20 along the shaft 16 ythethreaded member 56 is turned forcing the brake bands 58 sidewise againstone of the anges or friction wheel 60. It is immaterial if the brakebands 58 are tight or loose during the positioning operation 3 as longas the brake remains in the groove of friction wheel 69.

The clamp S4 can be moved along the shaft 16 to accommodate paper rollsof different axial lengths. This feature of my invention is animprovement over the fixed standards of the prior art.

Although I have shown only one intermediate sleeve 20 it will beapparent that more sleeves can be mounted on shaft 16 by the use of morethan one clamping device 54.

It will be noted that paper strips 30 and 32 are being drawn off thebottom of the rolls and 12 while the paper strip 34 is being taken offthe top of roll 14. This makes rolls 10 and 12 rotate in the directionindicated by arrows 37 and 41 and roll 14 rotate in the directionindicated by the arrow 4t). independent rotation of the paper rolls isdesirable because paper has sides of slightly different quality. Oneside is the felt or watermark side; the other side is the wire side. Thepaper sides are so named because the paper during manufacture contactsfelt on one side and wires on the other.

If for any reason one roll of paper is wound felt side out and theadjacent roll is wound wire side out it will be apparent that they canbe made to unwind and deliver strip paper with the desired side facingupward if the paper rolls can be made to rotate in opposite directions.This is one of the results my invention accomplishes.

For example, if paper rolls 10 and 12 are wound wire side out and paperroll 14 is wound felt side out and if the rolls are placed on the shaft16 so that the roll 14 will rotate clockwise by pulling the paper in thedirection shown (as one looks endwise at the rolls from the standard 36)and rolls 1t) and 12 rotate counterclockwise, the paper strips 36, 32and 34 will all face felt side up as they move to the next operation.

It is also possible to play off paper from one roll with one paper sideup and from one or more rolls with the other paper side up at the sametime to meet specific mill orders.

It should be noted that the paper roll rotation can be determined by howone places it on the shaft. A change in roll mounting end for end willgive a 360 change in the direction of the rotation. An end for endchange in roll mounting also results in a change in paper payoff fromthe top to the bottom of the roll and vice versa.

It will be obvious that the independent rotation of each roll of paper,permitted by my invention, will allow roll 12 to turn faster than roll10 and roll 10 to turn faster than roll 14 for a constant linear speeddelivery of paper strips to the following machinery (not shown) which isdrawing off the paper strips. The smaller a roll the faster it mustrotate to keep its linear paper delivery equal to that of a larger roll.

The shaft 16 is held stationary by arms or outriggers 64 which engagefacets 42 on shaft 16. The arms 64 may be hinged to assist the operationof changing rolls. The end brake or friction wheel, as wheel 28, areprovided with externally contracting brake bands which are supported andprevented from turning by arms 66, The end brakes may be adjusted toprovide the desired retardation to the end rolls 10 and 14 by tighteningbrake band adjustment screws 29.

In FIG. 2 it will be observed that the shaft 16 may be provided with arounded or sharpened ends 45 to facilitate insertion of the shaft 16 inthe sleeves 18, 2t) and 22. The sleeves are rotatably mounted on theshaft by means of bearings such as the bearing 50 and 52 of sleeve 18.The bearings are fastened to the sleeves by and suitable means.

The paper rolls are mounted on the sleeves in such a manner that therolls will be carried by the sleeves and will rotate with the sleeves.One way this result may be obtained is through the use of removablecollars such as the collars 24 and 26 applied to paper roll 10. Thecollars 24 and 26 may be provided with lugs 46 and 48 respectively,which engage the paper roll and prevent relative movement between theroll 1i) and the sleeve 18.

The collars 24 and 26 and rings 31 may be removably mounted on thesleeves so that the paper rolls may be placed on the sleeves by slidingand sleeves into the paper rolls. After the sleeves are inserted in thepaper rolls the removable elements such as collars 24 and 26 and rings31 may be positioned and held in place by any suitable means such asallen screws.

It should be noted that my invention may be easily adapted to hold oneroll of long axial length by using but one sleeve almost as long asshaft 16.

Referring to FIG. 3 it may be seen that the sleeve 18 is allowed to movethrough the friction Wheel'28 by means of the slot or keyway 72 in thesleeve 18 and the key 70 in the horizontally xed rotatable frictionwheel 28. The same arrangement is used to allow movement of sleeve 22along the shaft 16. As previously mentioned, the end friction wheels areprovided with externally contracting brake bands which are held in placeby rigid arms 66 as best seen in FIG. l. Any intermediate frictionwheels, such as wheel 6i), do not require a slot arrangement because thewheel 60 is carried on the sleeve 20 and is attached to it by anysuitable means such as welding.

My invention has the additional feature of allowing a plurality of rollsto be mounted on the shaft 16,4 each in the manner of roll 12, if theslot arrangement is not desired.

It can be seen from FIGS. 1, 2 and 3 that I have provided an improvedholder for paper rolls that will permit more than one roll of paper tobe mounted on a single shaft even though the rolls are of differentdiameters and different axial lengths.

My invention also eliminates the need for intermediate supports betweenthe end standards.

It will, therefore, be apparent that there has been disclosed a multipleroll paper holder which is more versatile than the single roll paperholders of the prior art.

Since numerous changes may be made in the above described apparatus anddifferent embodiments of the invention may be made without departingfrom the spirit and scope thereof, it is intended that all mattercontained in the foregoing description as shown in the accompanyingdrawings shall be interpreted as illustrative and not in a limitingsense.
